I could not reproduce your problem with the current version (Revision 1.460)
under Linux. I guess you made sure that user "nobody" and group "essadm" exist.
Try to run elogd interactively, if you see any error message (without "-D"
flag). In the most recent version (1.460), I added some more debugging code
which tells you if elogd successfully fell back to another user, if you use the
"-v" (verbose) flag.

If all that does not help, I guess it's some peculiarity of Solaris. Maybe
someone else using Solaris has some idea. All elogd does is a call to 

setuser("<user>");

I see no reason why this should not work on Solaris.
